    need help replacing ecm

    I want to replace the ecm in my 1998 corvette with a backup ecm I have
    from a 1997 corvette both are licensed through hptuners. I will flash the custom tune I have on my 98 ecm on to the 97 ecm but what about the vin? Does that need to be changed? I switched them out but there was no power at the ob2 port? Could it be because the vin # does not match? Thanks

    sounds like a fuse to me. Check the Cig lighter fuse.

    Don't flash the 97 ECM with the 98 file, you may burn it.
